The film 1 is clamped on the K surface the clip main body 41 by lowering the clip lever 42 by the lowering device and the film 1 is drawn. Clamping the film 1 is released by pushing up the clamp lever 42 at the exit of the drawing machine. The surface pressure on the sliding surface between the clip main body 41 and the rail 46 is reduced by means of mutual repulsing force of the magnetic force generating devices 51-54 as far as the tensile force of the film acts on the clip main body 41 and the clip main body 41 is thereby smoothly driven along the rail 46.
